Abstract: A machine is disclosed, for making a groove into a ceiling, a wall or a floor. The machine has a powered truck-like vehicle having a support base and an apparatus mounted on the base. The apparatus has two parallel spaced-apart booms pivotally mounted on the base and a holding head slidably mounted on each boom. An elongated main rail mounted on the heads in such a way that it may rotate about a longitudinal axis parallel to itself. A saw carrier is mounted on the main rail and a motorized saw is mounted on the saw carrier. The saw carrier can move along the main rail and the saw can be displaced on the saw carrier in a direction perpendicular to the longitudinal axis. The main rail is mounted on the heads with curved support members which are each pivotally connected to the respective head for rotation about the longitudinal axis. Each curved support member has a first end on which the main rail is mounted, so as to allow the main rail to pivot about a transversal axis perpendicular to the longitudinal axis. Each curved support member has a second end linked to the respective head in such a way that the curved support member can pivot about in connection to the respective head for levering the first end of the curved support member and, therefore, for rotating the main rail about the longitudinal axis.  Each opposite end of the main rail preferably has an extendible leg for stabilizing the apparatus whenever required. This leg can be oriented in a third direction perpendicular to the longitudinal axis and perpendicular to a surface. Each leg can be attached at two different places in such a way that it extends more or less further.

Title: Process for preparing 1,3-propanediol
Inventor: EUBANKS DAVID CLEVE
IPC: C07C29/16
Filed: 1997-03-06
Abstract: 1,3-Propanediol is prepared in a process in which ethylene oxide is reacted with carbon monoxide and hydrogen in an essentially non-water-miscible solvent in the presence of an effective amount of a non-phosphine-ligated cobalt catalyst and an effective amount of a catalyst promoter under reaction conditions effective to produce an intermediate product mixture comprising less than 15wt.% 3-hydroxypropanal. The 3-hydroxypropanal is extracted in water from the product mixture in more concentrated form, with the majority of the cobalt catalyst remaining in the solvent phase for recycle to the hydroformylation reaction.  At least a portion of any residual catalyst in the water phase following extraction is removed by re-extraction with non-water-miscible solvent and recycled to hydroformylation. The 3-hydroxypropanal is then hydrogenated in aqueous solution to the desired 1,3-propanediol.

Patent CA-2260399-A1 (CA)
Title: Solar water purification cone
Inventor: DONNAN DAVID W
IPC: F24S20/20
Filed: 1999-01-19
Abstract: "The Solar Water Purifying Cone" utilizes four different methodologies. The sun light is reflected by means of a cone made up of 8 to or more sides (31). (formula for calculating the no. of sides = the circumference / the dia of the middle core, rounded to the nearest even no. upward). Sun light is diverted @ right angles to the reflective sides (2) which are at 45 degree angles. After the sun light is diverted, it is focused through a magnifying collar (23) into 100 to 400 plus burn points, which focus through a glass sheath (17) onto the center core (18). The center core is made of copper coiled lobe (11) to which fluid travels through. These copper coils (11) are coated with a powder black coating able to withstand 1000 degrees of heat. The color black is used based on the known theory that black attracts or absorbs heat (11). The glass sheath (17) is fitted over the black coils as tightly as possible, this acts like a green house around the core (18). This glass sheath (17) shields the center core (18) from any wind. The magnifying collar (23) has a row of magnifiers (21) for each side of the reflective cone (31), this process focuses sun light into defined burn points which go through the glass sheath (17) onto the center core of copper coils (11). The coils (11) are bent around a hollow pipe (8) which is fastened to the center of the reflector cone (31). The reflector panels (1,2) are held in or on a steel frame (3) which pivots (27) on a steel tubular stand (28).  This process and device also what we have termed as " Solar water purifying distilling condenser". With the same device, the center core (18) is cooled as the outside is heated by the reflective cone (31). There is a condensing of any humidity in the air which collects rapidly on the coils (11). Since this water has already been distilled by mother earth, this process is actively amplified by the cooling and heating of the coil center core (18). This device can boil water through the coils (11) or produce steam which will distill water or collects humidity from the air which condenses on the core coils (11) to water. The device is focused into the sun by means of a single magnifying glass (32) that produces a sun dot on the face of the middle core top plate (10). The device is positioned so that the dot is in the center of the core face (10,18).
